.LCQ'FZCA'IION forming part of Letters Patent No. 339,601, dated Application filed Octobcril, 181*5. Serial No. 178,858. (Xe lllhill'l.)

To all whom it may concern:

Be it known that I, Fninnniou Twiok, of Sheboygan, in the county of Sheboygan and State of Wisconsin, have invented a new and Improved Combined Land-Roller and Clod- Crusher, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved land-roller for breaking the lumps and clods of earth, and thus harrowing the land, which roller is so constructed that it can easily be adjusted for operation or transportation.

The invention consists in various conslructions and combinations of parts and details, as will be fully set forth and described hereinafter, and pointed out particularly in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figures 1 is a side view of my improved landroller, the rollers being raised and the do vices adjusted for transportation. Fig. 2 is a cross-sectional view of one end part ofthe same. Fig. 3 is a crosssectional view of some of the rollers, showing the manner in which they are mounted. Figs. 4: and 5 are sectional end views Fig. (3 is a plan view of part of the machine. Fig. '7 is a longitudinal view of a shaft and a series of colters on the same.

In the side pieces, A, of a frame, in which frame the draft-pole B is secured, the two shafts O are mounted, extending parallel with each other from side to side of the frame, and on each shaft a series of cutter-disks or coltcrs, ]),are mounted, which have their edges beveled or curved to form sharp cuttingcdges and large annular grooves or cavities between the cutting-edges of the adjacent disks. The disks are mounted on the shafts U in such a manner that they interlock-that is, that the cutting edge of one disk passes into thcannulargroove, recess, or cavity between the cutting-edges of the adjacent disks on the other shaft. A suitable washer, D, having a neck provided with a set-screw, is interposed between the end disk, D, and the side pieces of the frame A. Said disks are all mounted loosely on the shaft 0, and said sl'iaft is journaled in suitable boxes,

E, on the bottom edges of the side pieces of the frame.

011 the central portion of each side piece, A, a metal plate or piece, F, is secured, from which a standard, G, projects upward, and in said standard and plate a screw-spindle, H, provided on its upper end with a cross-piece or handle, H, or a hand-wheel of any suitable shape or construction, is mounted to revolve on its longitudinal axis, said spindle being provided on its lower end with a head, H which is below the top part of the plate F and in a recess in the top of the side piece, A, the spindle being screwthreaded from the top of the plate F up to the top crosspiece on the standard G. Said screw-spindle only revolves on its longitudinal axis, and does not travel in the direction of'its length. Aunt, J, through which the screw-spindle H is passed, is formed as an arm on the upper end of a plate, K, sliding on that portion of the plate F on the outer surface of the sidepiece, A, and from theouter surface of the plate K apivot, L, projects near the lower end of said part K, and on said pivot a wheel, M, is mounted to revolve. A wheel is pivoted in this manner on each side of the machine, and by turning the screwspindlesH at the sides of the machine the sidepieces, A, can be raised and lowered in relation to the wheels, and, as the wheels are on the ground, the frame will also be adjusted in relation to the ground, and thus the coiters or disks D i can be raised more orless from the surface on which they are to act.

The colters or disks 1) may be adjusted to be a greater or less distance from the ground at one side of the machine than they are at the other.

Fig. (5 shows a machine having only two rows of colters or disks arranged in the manner set forth; but, if desired, additional groups of colters may be provided at the front and rear of the machine, said additional col ters or disks being arranged in groups of two or three, as shown in Figs. iand 5, and mounted on a shaft journaled in a vertically-sliding frame, N,on a guide,(), on the frame of the machine. The vertically-sliding frame N is connected with the lever P, which can be locked in place bya spring-catch, Q, as shown in Fig. 4, in which case the lever Pprojects transversely over the machine; or said levers may project toward the center of the machine. By raising the inner ends of said levers the additional colters or disks at the front and rear of the machine are lowered, and by pressing down the inner ends of said levers the colters or disks are raised.

When drawing the machine to the field to be harrowed, the wheels M are so adjusted that the disks D are above the ground, and when the machine arrives at the field the wheels are so adjusted that the edges of the colters D will cutinto the ground more or less, as may be desired, or as the nature of theland may require. The colters not only crush the lumps of earth, roots, 850., but they also cut them and pulverize the earth.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A combined land-roller and eled-crusher comprising the frame having verticallyadjustable wheels, the central series of intermeshing disks jonrnaled on the frame, and a smaller series of disks in front and rear of the main series, vertically-adjustable frames therefor, and operating-levers pivoted on top of the frame and to the said frames, substantially as set forth.

2. In a combined land-roller and eled-crusher, the combination,with theframe having vertically-adjustable wheels, middle shafts, O C, havinga series of disks,-D, formed with beveled edges, the cutting-edges of one series of disks entering the spaces formed between the other series, of the auxiliary front and rear disks, D, mounted in the frames N, the guides O for said frames, and the operating-levers P, for raising the said frames N, substantially as set forth.
